Bile Duct Tumors Tumors of the bile duct constitute about 2% of all cancers found at autopsy. Benign adenomas or papillomas are exceedingly rare compared with malignant tumors. Even benign tumors tend to recur after excision and have been reported to undergo malignant change. Patients usually present with jaundice.

Gallstones More detailed description about gallstone disease. Gallstones are solid crystals of various salts that accumulate in the gallbladder or the ducts which transport the bile from the liver or into the intestines. Often, they cause no symptoms at all; they can, however, trigger a very severe attack.

Leiomyoma From Wikipedia, the free encyclopedia. A leiomyoma (plural leiomyomas or leiomyomata) (leio- + myo- + -oma, smooth-muscle tumor) is a benign smooth muscle neoplasm that very rarely becomes cancer (0.1%). They can occur in any organ, but the most common forms occur in the uterus, small bowel, and the esophagus. Leiomyoma enucleated from a uterus.

Gallbladder polyps, cholesterolosis, adenomyomatosis, and acute acalculous cholecystitis. Cholesterolosis and adenomyomatosis of the gallbladder are usually clinically silent and incidental findings at the time of cholecystectomy. Cholesterolosis is characterized by mucosal villous hyperplasia with excessive accumulation of cholesterol esters within epithelial macrophages.

Hepatomegaly Hepatomegaly is the condition of having an enlarged liver. It is a non-specific medical sign having many causes, which can broadly be broken down into infection, hepatic tumours, or metabolic disorder. Often, hepatomegaly will present as an abdominal mass. Depending on the cause, it may sometimes present along with jaundice.

Oncocytoma Oncocytoma can be described as a tumor that is mainly constituted out of oncocytes. These are actually epithelial cells, containing excessive quantities of mitochondria. This excess leads to a cytoplasm that is acidophilic and granular.

Acute cholecystitis Acute cholecystitis. Acute cholecystitis is inflammation of the gallbladder. It usually occurs when a gallstone blocks the cystic duct. Gallstones are small stones, usually made of cholesterol, that form in the gallbladder. The cystic duct is the main opening of the gallbladder.

Gallbladder - Wall Thickening Chronic cholecystitis is a term used clinically to refer to symptomatic gallbladder stones that cause transient obstruction, leading to a low-grade inflammation with fibrosis [1]. Correlation of the imaging finding of a stone-containing slightly thick-walled gallbladder with the clinical history is critical.

- Uterine leiomyomas (fibroids or myomas) are benign tumors. Since histologic confirmation of the clinical diagnosis is not necessary in most cases, and there is both growth and regression of fibroids, asymptomatic uterine leiomyomas can usually be followed without intervention [1].

Adenomyomatosis They may be microscopic or macroscopic. Histologically, they are outpouchings of gallbladder mucosa into the gallbladder muscle layer and subserosal tissue as a result of hyperplasia and herniation of epithelial cells through the fibromuscular layer of the gallbladder wall. They are usually referred to as adenomyomatosis.

Cholangiocarcinoma Cholangiocarcinoma is a form of cancer that is composed of mutated epithelial cells (or cells showing characteristics of epithelial differentiation) that originate in the bile ducts which drain bile from the liver into the small intestine.ther biliary tract cancers include pancreatic cancer, gallbladder cancer, and cancer of the ampulla of Vater. Cholangiocarcinoma is a relatively rare neoplasm that is classified as an adenocarcinoma (a cancer that forms glands or secretes significant amounts of mucins).

Gallstones Gallbladder Polyps. Polyps (growths) are sometimes detected during diagnostic tests for gallbladder disease. Small gallbladder polyps (up to 10 mm) pose little or no risk, but large ones (greater than 15 mm) pose some risk for cancer, so the gallbladder should be removed.
